The Gym Group, a leading high value, low cost fitness operator and biggest National HYROX Training Club in the UK, has successfully scaled HYROX group training across more than 120 locations through the HYROX365 Performance Hub, built in collaboration with fitness tech leader ONE FIIT.
The goal? Deliver consistent, high-quality training experiences to thousands of members while making the rollout simple and cost-effective for staff.
The HYROX365 Performance Hub offers:
- Eight workouts per week designed by HYROX’s programming experts
- Coach-facing training notes to boost delivery quality
- Equipment filtering tools for gym-specific setups
- Consistency and community across all gym locations
Jenni Tardiff, National Group Exercise Manager at The Gym Group, said: “We knew there was demand from our members for HYROX-style workouts and ONE FIIT made it easy for us to scale while ensuring our trainers had the tools and confidence to deliver standout classes.”
Chris Hall, General Manager at The Gym Group Chichester (pictured), added: “My HYROX classes are more varied, engaging, and accessible. The filtering feature makes my life easier as a coach. Members keep coming back – and they’re performing better too.”
Ian McCaig, Founder and CEO at ONE FIIT, said: “We built the HYROX365 Performance Hub to solve a real challenge: how do you scale premium group training without compromising on quality or overwhelming your team? The Gym Group’s success shows what’s possible when you give trainers the right tools and programming. You get consistent experiences, engaged members and classes that practically run themselves.”
